Phoenix Contact 2744458 RS232 to TTY Interface Converter
The Phoenix Contact PSM-ME-RS232/TTY-P interface converter provides a reliable solution for converting RS-232 (V.24) signals to TTY current loop signals. This converter is designed for industrial environments, offering electrical isolation up to 2 kV and supporting transmission distances of up to 1000 m in active TTY mode. It is rail-mountable, facilitating easy integration into control cabinets. The converter's versatility allows for active, semi-active, or passive TTY mode operation, adapting to different pin assignments and cable lengths. It is ideal for connecting legacy RS-232 devices to systems utilizing TTY interfaces, commonly found in industrial automation, process control, and building automation applications. The integrated surge protection and data indicators enhance reliability and ease of troubleshooting.
